Odd subwoofer "breathing" when sound stops should I be worried?

[QUOTE="gamehawk55, post: 8049776, member: 645990"] SSF is on 30hz. Not sure how to test for a ground loop?. If it makes any difference all my grounds on a DMM are 0.4ohms or less with the exception of one being 0.6ohms on the longest ground wire of my BIG 3. Resistance of amp ground to chassis is 0.0ohms. I will also notice this happen sometimes with a quick hard bass hit that has no resonance behind it. I use my Ipod exclusively for music. Deck is a Kenwood DDX419 (see sig). Highs are not amped since I do not have aftermarket speakers yet (see sig) Was playing the -3db tones off of USB stick. Tones were created online using a tone generator to make the -3db tones. Tones used for tuning were on the SMD CD that came with the DD1. Also I don't think the RCA's for the sub are cheapo ones. I bought them at a Local shop here and they are double or triple shielded type. THICK cord. I would say 6-8Gauge in size.
